.-'QECFICATION forming part of Letters Patent No. 332,469, dated December 15, 1885.

Application filed March 11, 1885. Serial No. 1511,4C8. (No model.)

To aZZ whom, it may concerne' Be it known that I, ANDREW YoUNr, a citizen of the United States, residing at Denver, in the county of Miami and State of Inl diana, have invented certain new and useful Improvements in Corn-Planters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in corn-planters; and it consists in the peculiar construction, arrangement, and combination of parts, as more fully hereinafter set forth and claimed.

Figure l' is a side elevation, partly in scction, and with portions broken away to show the details of construction. Fig. 2 is a transverse sectional detail. Fig. 3 is a top plan of the rotary feed-disk,with portions broken away to show its driving mechanism. Figs. 4, 5, and 6 are detail views. j

The main frame A is supported in the rear upon the crank-axle C, provided with the drive-wheels B upon its crank-arms c, and forward by the runners H. The tongue D is connected to the main frame by links I and K, the former joining the frame and tongue direct, and the latter joining the rear end of the tongue to the axle C. A lever, J, mounted upon the axle C, which is its fulcrum, its lower end connecting with the tongue and its upper end within easy reach of the driver, serves as a means to raise and lower the main frame at will. By reason of the links I and K running in the same inclined position, the frame, in its rising-and-falling movement, will move in nearly parallel planes. The frame may be held at any desired position by the latch j of the lever J engaging a notched segment, J', on the main frame.

Centrally supported by the bracket M' is the grain-hopper M, provided with a suitable cover. Its bottom Q, is diametrically apertured, as at A", from each of which extends a conveyer, O, to a spout, N, one on either Side of the machine and slightly in advance of and in alignment with the tread of the carriage or carrier wheels. Resting upon the bottom Q, and attached to the upper end of a vertical shaft, S, is a revoluble disk, R, having apertures at stated intervals around close to its periphery, which register with the openings A" in the bottom lof the hopper. Keyed'to the shaft S is a ratchet-disk, Q', motion being communicated thereto by pawls U, engaging the disk in opposite directions, and loosely attached to the opposite sides of a slotted arm, T, working on the shaft S. The outer end of the arm T connects with the end of a lever, V, pivoted to the main frame, its lower end being provided with a swivel, t, which runs in the cam-grooves of the block Y, the latter being mounted upon a shaft, NV, having one end journaled in a boX, Z, swiveled in the hanger Z', attached to the main frame, the other end having a grooved pulley, E', secured thereto. Said pulley is centrally recessed to receive a disk, E", keyed to theinner end of a shaft, WV', in axial line with the shaft XV, the two being held in frictional Contact by a disk, E"', sleeved on the hub of the diskl and `joined to the disk or pulley E by bolts. The disk E" is of less diameter than the recess in the pulley, in order not to interfere with the bolts. To increase the friction betweeng the pulley and disk, leather Washers e are interposed between the parts. To the outer end of the shaft W', which is mounted so as to have a free vertical movement in accordance with the unevenness of the ground over which the machine is moving, is a sprocket-wheel, F, mounted so as to rotate with its shaft. An endless chain band provided with blocks G,secured thereto at stated intervals by bolts G', passes over this sprocket-wheel, and over a similar one, F', mounted in a like manner in the rear of the machine.

In practice, the machine being drawn forward, the blocks G and the ends of their bolts G', contacting with the ground, will impart a rotary movement to the shafts W' W, and to the cam-block Y, the latter oscillating the lever V, which in turn will reciprocate the arm T, thereby imparting an intermittent rotary movement to the disk R, which, as each successive opening registers with the openings A", will deposit its grain in the conveyors O grain being deposited in the ground on eitherside of the machine at one and the same time.

As the grain is deposited in advance of and covered by the drive-wheels, it is necessary, in order to have the grain planted in rows, to

determine the points of deposit. This I ac-.

complish by having a marker, D', to indent the earth at such points, connected to the horizontal arm of a bell-crank lever, C', pivoted .to the main frame, its vertical arm being connected to a rod, B', carrying a friction-roller, b', on its outer end to engage a cam, A', Secured to the shaft W, the parts being so timed and arranged that lthe marker D will exactly indicate the spot where the grain is deposited;

As the deposit of the grain is regulated by the relative` positions of the shafts W W, which are united and caused to revolve together by frictional contact, this frictional contact is easily overcome and the relative positions of the shafts regulated and adjusted by moving the pulley E either to the right or left; and in order that this may be easily accomplished by the drivel` without leaving his seat an endless chain, l2, is passed around the pulley E', and over a pulley, X, mounted on an arm, X', branching from the drivers seat.

As the distances apart at which the grain is deposited depend upon the diameter of the sprocket-wheels, the same are made interchangeable.

I claiml. The combination, with the shafts WW and friction-pulley clutch E E, of the endless chain I2 and the pulley X, as and for the purposes set forth.

2. In a corn-planter of the character described, thc combination, with the main frame, its supporting wheels, and runners, of the draft-pole, the front link connecting the pole directly to the main frame, the rear link connecting it to a crank-aXle, the hand-lever and latch, and the notched segment, as and for the purposes described.

3. The combination, in a corn-planter, of a main frame, mounted as described, a grainhopper centrally located and provided with laterally-curved conveyers leading to vertical discharge-tubes in line with the coveringwheels, the vibrating discharge-valves in the said tubes, an intermittent grain dropping disk on the perforated hopper-bottom, and the devices described for actuating the said disk, substantially as specified.

4. The combination of a grain-hopper having a perforated intermittently-rotating dropping-disk on a shaft, S, the ratchet-disk, the slotted arm-bearing pawls', the lever V, bearing a swivel, t, and a cam-block, Y, applied on a shaft, W', mounted as described.

5. The combination, with the grain-spouts N, of the vibrating valves P, their connecting-rod P, vibrating lever 19, actuated as described, and transmitting intermittent rotationto the dropping-disk by devices described.

6. The combination, in a corn-planter, of the two shafts W W', journaled in the same axial line and bearing a sprocket-wheel, with a compound friction-pulley, an accommodating bearing, Z, and a cam-block, substantially as and'for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.

A ANDREW YoUNT.
